So... 57fenderjazz get my 10 points and the other one with the 4 banger looking like a 5'er get nil points! Sorry.
kevin,
Just shell out for a new bass. No you can't buy a neck separately anyway from EBMM, and no the mutes will not fit your bridge either.
bpwb,
If you don't want the mutes on anymore, unscrew the bridge and remove the mute plate, then reinstall your bridge.
